The data center skilled trades shortage is affecting project timelines and extending backlogs to nearly a year. Firms are having a hard time finding well-trained electricians, low-voltage technicians, critical facility operators, and building automation specialists. To secure capacity, employers must build strong talent pipelines for the professionals who sustain the data center lifecycle.

The Buildout Is Accelerating Faster Than Any Prior Infrastructure Cycle

Data center construction is scaling so quickly that the workforce can’t keep up. A closer look at the number reveals the size of the data center workforce gap and how it’s affecting project completion timelines.

As of late 2025, the US faced a shortage of 439,000 construction workers. This gap is even more acute in skilled roles critical to the construction and operation of data centers. Besides reporting backlogs, firms mention delaying project starts. In extreme cases, contractors walk away from opportunities because they don’t have a workforce to deliver.

While labor shrinks, the demand for skilled personnel is increasing. Construction sites used to require a few hundred workers to complete a project. However, data centers may need upwards of 4,000 people.

Yet, investments aren’t the problem. According to McKinsey, global data center spending may reach $6.7 trillion by 2030. North America alone will receive approximately $1 trillion over the next few years. It’s clear that the scale of demand is locked in.

These stats show labor is the primary constraint. Firms need to partner with providers that understand the labor shortage dynamics and offer a reliable pipeline that steadily supplies the required talent.

Layer One: Electricians and Low-Voltage Technicians

Electrical infrastructure is the beating heart of a data center. Hyperscale campuses handle massive power loads, some requiring between 300 and 600 megawatts. Electricians install systems that distribute that power and conduct necessary tests to ensure that each part works. Low-voltage technicians are equally important and handle fiber and structured cabling that connect systems.

These roles aren’t just essential; they are critical. Without them, the data center won’t turn on.

During data center construction, electrical work accounts for 45% to 70% of the costs. The requirement makes them one of the most constrained parts of the workforce, as they are central to the building process. But there’s an emerging issue.

The electrical works workforce is aging out, with roughly 30% of electricians nearing retirement. Every year, 20,000 electricians leave the field. As a result, about 300,000 personnel will need to join the industry over the next decade to meet demand for low-voltage technicians.

This technician shortage in data centers isn’t just a statistic; companies are already feeling the pinch. 

Notably, it’s impossible to substitute electricians with adjacent trades. Also, you can’t delay their work without delaying the entire project. That makes the stretched labor pool a serious concern.

Layer Two: Critical Facility Operators and Building Automation Specialists

Once the data center is built, it requires a skilled operations team to activate and keep it running. Critical facility operators and building automation specialists are the professionals who maintain uptime. They ensure power flows and temperatures are optimal, and monitor infrastructure with no margin for error.

These roles require multiple skills. Operators must understand how power distribution and monitoring systems work. Building automation specialists are experts in HVAC systems and smart monitoring platforms. With a shortage of skilled trades in AI infrastructure, fully built data centers can’t operate.

While labor constraints on the construction side are significant, shortages in the operations sector are equally severe. A third of the workforce eyes retirement, and there isn’t a stable pipeline to provide fresh talent. Data centers sometimes take nearly 60 days to hire, since only 15% of applicants have the necessary qualifications to do the job.

The operations staffing gap directly impacts reliability. The Uptime Institute’s 2025 Annual Outage Analysis found that nearly 40% of organizations suffered a major outage caused by human error over the past three years, with 85% of those incidents stemming from staff failing to follow procedures. Uptime noted this rise may be a consequence of rapid industry growth and the resulting staff shortages.

The Structural Problem: Circulating a Small Pool Does Not Grow It

Companies are resorting to familiar but inefficient strategies to address the data center construction labor shortage issue. Salary increases, talent poaching, and incentives are all in play. However, these actions only redistribute talent rather than expand it.

The numbers show that these strategies aren’t working. Over 45% of companies are struggling to hire, and roughly 37% find it difficult to retain new employees. As companies strive to fill open roles, workers leave their jobs for similar positions at companies that offer better perks. Firms end up in a cycle of backfilling positions, disrupting workflows.

Competing industries also add pressure to the already acute building automation specialist shortage. Utilities, manufacturing, and renewable energy sectors are all drawing from the same limited pool of skilled trades workers.

Traditional apprenticeships, which take 4-5 years and require over 2,000 hours per year to train a person, aren’t designed to keep up with current demand for skilled trades workers. A pipeline that produces talent requires alternative pathways that operate at speed and scale.

Per Scholas Is Building New Supply

The labor shortage issue isn’t because companies can’t access talent. Rather, it stems from the fact that the workforce isn’t expanding at the rate companies require.

Per Scholas is creating a net-new supply of talent through programs designed around the specific roles employers are struggling to fill. The training offered maps directly onto the skills required to build and operate a data center. It’s a practical approach to current labor demands. 

In 2025 alone, 237 learners completed immersive data center-focused programs, achieving a 92% graduation rate. Since 2022, more than 200 professionals have been placed directly into data center career pathways.

Per Scholas partnered with TEKsystems to support the hiring of over 1230 personnel in 12 markets. Employers report a 35% higher retention rate and shorter time-to-hire than with traditional talent pipelines, reducing hiring costs.

The hallmarks that make Per Scholas training programs so effective include a faster turnaround time to job readiness. In 15 weeks, learners receive immersive training on power management, HVAC systems, building management systems, and AI-enabled monitoring, and can work as critical facility technicians. It takes about the same amount of time to train building automation specialists. However, the Low Voltage Telecom program, which targets fiber, cabling, and telecom infrastructure, takes only six weeks.

Additionally, all Per Scholas programs are instructor-led and mirror real-world workflows, featuring two years of ongoing alumni upskilling.

Moving From Constraint to Solution

As data center expansion accelerates, the primary constraint remains skilled trades shortages. Investments are flowing, but projects are lagging because the workforce tasked with bringing them to fruition is insufficient. The problem is the pipeline, and companies that treat it that way will be better positioned than those waiting on the open market.

Per Scholas works with employers to build pipelines of trained critical infrastructure technicians aligned to real operational requirements. If workforce constraints are slowing down your data center projects, let’s talk.
